HURRY HELP Question
Students in a lab have tested boiling points for 10 different substances that are liquids at room temperature. They now want to study melting points. Which obstacle might they face that would prevent them from collecting data?(1 point)

Depending on the amount of each substance they have, it might take a very long time for the substances to completely melt.

Some liquids might have melting points that are far lower than room temperature.

They might collect new data that changes the average for the experiment they have completed.

Some of the liquids might melt at a temperature that is too high for the thermometers they are using.
